TO ALL TO WHONI THESE PRESENTS SHALL COME:

Be it known that EDWARD FITZIIENRY,`of Boston, county 0f Suiolk, and State of Massachusetts, have invented a new and useful Improvement in Machines for'Dressing Leather; aud'do hereby declare the following i to be a full, clear, and exact` description thereof, reference being had to the accompanying drawings, making part ofv this specification, and in which-4 Figure 1 is atop view. Figure 2, a side elevation. Figure 3, e. vertical and longitudinal section of the invention. Figure 4 shows a modification of thc invention, to be hereinafter described. lMy present invention is an improvement upon that for which Letters Patent of the United States have recently been ordered to issue to me for scouring and sleeking leather, etc. As therein' exhibited, the tablet for receiving the skin is supported by and placed directly upon the top of the sta-ging or frame, and so that the under surface of the tablet comes in direct Contact with the upper surface of the staging.

p The object of my present invention or improvement Lis' to materially reduce the friction consequent upon this arrangement of the tablet and its supporting frame.

.The following description, withv the aid of the accompanying drawings, will clearly exhibit the improvement. As therein shown, the staging or fra-me for supporting the operating tablet, is composed of a number of radial arms or rails, A A, etc., ete., clivcrging from a central standard, a, the outer extremities of these rails being duly supported by a series of posts, b b, etc., arranged coneentrically about the standard a. A range, c, of hemispherical recesses is formed in the upper surface of each rail to receive a number of spherical anti-friction balls, dd, ete., as represented. The tablet for supporting the skin and moving it about under the action of the macbine,`is shown at a es supported upon the upper surface of the balls (Z c?. The movement of the tablet in any direction will cause a rotation ofthe balls within their recesses. It u'ill be seen that the employment of those balls, as described,ver)Y much reduces the friction between the tablet and its supporting` frame, and allows the tablet to be moved about therein withcomparativc ease, as contradistinguished from the construction and arrangement, as shown in the machine to which reference has hcreinbefore been made. I would remark that instead of applying the spherical balls directly'T to'thc rail, as shown in iig. 3 of the drawings, I have contemplated the employment of a'series of semicircular cups,4 applied to therailby means of ashank extending fron*` the under Side ofthe cup and through the rail, and having a nutupon its lower'end to screw against the rail, as represented in iig. 4. l

I claim, as an improvement in the machine for scouring and sleeking leather, constituting the subject of the invention before referred to, and for which Letters Patent of the United States have been ordered to issue to ine- I v i The employment of the anti-friction balls, or -their equivalents, substantially in manner and for the purpose as hereinbefore described.

EDWARD FITZHENRY.
